This invention refers to improvements in closures for metallic barrelsor containers, and the principal object of the invention is to providean air and liquid tight seal for the central opening in the closure,which may be easily placed and removed.

Closures for metallic barrels or containers generally consist of threepieces, namely one piece which passes through the cleanoutopening in theupper wall of the container and is kept in position by a plate, whichrests on the outer surface of the upper wall of the container, and thefirst mentioned piece is moved into close contact with the inner surfaceof the upper wall of the container to close the cleanout-opening insame. The first mentioned piece is provided with a central bore taperingtoward the end disposedin the interior of barrel 1 and through which thecontents of the container are drawn. The present invention refers toimprovements in the closing means for said central perforation. i

In the accompanying drawing I have shown such a combination of closingmeans for the cleanout-opening, and for the central perforationfor'extraction of the con tents of the container.

In the only figure of the drawing, 1 indicates the upper wall of thebarrel, or container; 2 indicates the cleanout-opening; 3 indicates themain piece of the closure, which is provided with a central bore 4. Theprincipal piece 3 is provided with an exterior flange 6 on its upperend, and the central bore is provided with an interior flange 5.

The lower part 9 of the principal piece 3 is somewhat larger than thecleanout-opening in the upper part of the container and is provided witha recess for receiving a rubber ring 10 which will bear against theinner surface of the upper wall of the-container. The principal piece 3is provided with exterior thread and passes through a plate 12 whichrests on the outer surface of the upper wall of the container. A nut 11placed on the exterior thread will bear against the plate 12 and thusforce the lower part 9 of the piece 3 against the inner surface of theupper wall of the container, the

rubber ring 10 making A the closure tight.

The improvements in the above mentioned closure consistingiving thepiece. 3 the form of'an inverted bottle neck at'its inner and' f'iinterior extreme end placing on said end an ordinary crown sealingdevice or diaphragm g an inner flange in the central perforation 4.

Hitherto the -c'entralbore of the piece 3 1.- was closed by means of acork. This closure would not be airtight and furthermore the removal ofsamewas not always easy.

The closure according to the present invention has the followingadvantages:

It effects an absolutely hermetic seal of the central bore 4; it iseasier to place and easier to remove; it is cheaper than the cork; noprior cleaning and preparing of the crown diaphragm being required.

As the principle of the invention is to place the crown diaphragm 8 inan inverted manner onto the flange 7, it will readily be understood thatany pressure from within the container will augment the sealing effectof the crown diaphragm 8, making the seal absolutely hermetic.

When the liquid of the container has to be used, it will be suflicientto introduce a tube or pipe in the upper endof the central open-1: ingor bore 4 and push it slightly against the crown diaphragm 8, which willeasily unfasten and fall within the container thereby permitting easyoutward flow of the liquid contents.

Having thus described my invention what I claim is: V

1. In a barrel or container, a closure device comprising a lower platehaving an upper and lower extension with a bored portion pro trudingabove and below said plate, an upper plate with an opening containingthe upper extension of the lower plate, said upper extension beingthreaded, and means for making engagement with the threaded portion ofthe extension whereby to bring the plates in cfiose contact against. thebarrel or container wa y 2. In a barrel or container, a closure deviceaccording to claim 1 having a flanged end on the lower portion of saidextension, and a leakage proof sealing member attached to said flange.

3. In a container for liquid commodities, a closure device for anopening in the container, comprising a lower plate having an upper andlower extension with atapered centrally bored portion protruding aboveand belowthe plate, the lower extension having an outer peripheralflange at its lower extremity, an upper plate with a central openingcontaining the upper extension of said lower plate, means around theupper extension for drawing the lower and upper plates toward each otherand against the inner and outer walls surrounding the opening of thecontainer, and a sealing diaphragm facing the interior of the containerand surrounding the outer peripheral flange to cover the bore of theextension whereby to close the. same and prevent leakage of the contentsof .the

. container.

In testimony whereof I have aifixed my signature. 7
